... farmers' boys, many of them have been brought up to all of the unscientific crudities which have been handed down in American agriculture since the early settlers took the land from the Indians in grateful recognition of their instructions in fertilization. While many agricultural anachronisms may be laid to the door of the redskins, planting by the moon and several equally absurd customs are traceable to the higher civilization of ...

... of the extrusion of polar bodies and fertilization are treated of later, and will, therefore, not be considered now. We will start our description with an egg-cell, which has escaped, of course, since there are no genital ducts, by rupture of the parent, has been fertilized by the male element, and is about to develop into a young ...

... the light application appeared almost to be adequate. In such land there cannot be full bacterial activity or continuing friendliness to plants unless the need is met fully. A larger application would have paid better. It is the soil rich in lime that can make the best response to tillage and fertilization. ...

... cases 23 were counted (fig. 94). This differs from McClung's count for similar cases among the Orthoptera, and Sutton's for Brachystola magna. The eggs have so far resisted all efforts to learn what part the odd chromosome may play in fertilization. ...

... way new strawberry plants were obtained. One shoot may be bent and buried more than once. So one may get just as easily two or more new plants from one shoot. This seems as much a miracle as the cross fertilization ...

... while in the male there is one odd one, the remaining 20 being like the corresponding 20 of the female. Before the germ cell becomes fit to mix with a germ cell of opposite sex, in the process of fertilization, it must lose one half of these. So the number of chromosomes for the species is kept the same or constant. This is the process of maturation. In the process, when the chromosome number is halved among ...

... had a solidarity of its own with national tendencies.[29:1] On the tide of the Father of Waters, North and South met and mingled into a nation. Interstate migration went steadily on—a process of cross-fertilization of ideas and institutions. The fierce struggle of the sections over slavery on the western frontier does not diminish the truth of this statement; it proves the truth of it. Slavery was a sectional trait that would not down, but in the West it could not remain sectional. It was the greatest of frontiersmen ...

... for cultivation of hickories has been worked out only with the pecan up to the present time. With this species, it has been determined that clean cultivation with plenty of fertilization gives best results, as with apples. It is probable that Stringfellow's sod culture method will come next in order, and will perhaps be most generally used by nut orchardists, because it is less expensive and requires less labor. The sod culture method includes the idea of cutting ...

... genus, in which the end of the spadix was prolonged into a very long, thread-like appendage thrown over the leaves of the plant or of its neighbors, and ultimately reaching the ground, and thus, it is presumed, affording ants and other insects means of access to the flowers, and consequent fertilization. These species were grown by Mr. Elwes, and exhibited by him before the Scientific Committee. The present species is of somewhat similar character, but is, we believe, new alike to gardens and to science. We met with it in the course of ...

... anything but so many calculated tons of leverage - what had she to do with these? Her remembrances of home and childhood were remembrances of the drying up of every spring and fountain in her young heart as it gushed out. The golden waters were not there. They were flowing for the fertilization of the land where grapes are gathered from thorns, and figs ...

... kinds of cover crops which may be used in the apple orchard will be considered in the next chapter as they are so closely associated with fertilization. Strictly speaking, however, a cover crop is used principally to secure its mulching and physical effects on the soil in the intervals between the seasons of tillage. In addition to its physical and feeding effects the cover crop serves to check the growth of trees in the latter part of the ...

... to conduct analogous examinations of prospective mothers; and surgery secreted in the ample and luxurious folds of anaesthesia, and protected by its guardian angels antiseptics, makes it possible to prevent the fertilization of human ova with a vicious taint. It is possible to sterilize defective women, and the wives of defective men by an operation of simple ligature, which produces absolutely no change whatever in the ...

... the soil in a state of fertility depends primarily upon fertilization. The obtaining of fertilizers is, accordingly, for future society also one of the principal tasks.[200] Manure is to the soil what food is to man, and just as every kind of food is not equally nourishing to man, neither is every kind of manure of equal benefit to the soil. The ...

... dust to enter the pistillated flower without fulfilling the important duty designed, and leave a portion of the fertilizing dust in its proper place. Hence it is reasonably inferred by many, that if it was not for this agent among our vines, the uncertainty of a crop from non-fertilization would render the cultivation of ...
— Mysteries of Bee-keeping Explained • M. Quinby
... large garden varieties are rarely self-pollinated, even if left uncovered, but the chances of fertilization with inferior kinds, generally the most abundant pollen producers, are so great that it is well to protect all seed-bearing blooms from insect interference. If the work is to be done on a large scale sleeves of netting or muslin large enough to enclose ...

... similar dislocation of the normal balance. The acute question will be repopulation—with a view to another trial of military supremacy a generation hence!—and all sorts of expedients are being suggested, from polygamy to artificial fertilization. It may be that the whole future of woman as well as of civilization after this war is over depends upon whether she concludes to serve the State ...

... into the womb. After they have arrived in the womb they are, as a rule, cast off with the secretion and leave the body. If in the course of its travel from the ovaries, through the tube to the womb, the female ovum or egg meets with the male elements, fertilization or impregnation may take place. If then it is not cast off it generally lodges in the womb and pregnancy has begun. The male and female elements are usually supposed to meet in the outer portion of the Fallopian tubes, fertilization then taking place; but this can occur any place from the ovary ...

... native forests. [Footnote: Mantegazza, Rio de la Plata e Teneriffa, p. 567.] In China, too, rock has been artificially covered with earth to an extent which gives such operations a real geographical importance, and the accounts of the importation of earth at Malta, and the fertilization of the rocks on Mount Sinai with slime from the Nile, may be not ...

... insensate, we find the universal law of sex-attraction and repulsion. The pollen from an oak tree, for example, may be blown about by the wind and may light upon a plant which is far removed in species from its own; but if such be the case, no fertilization takes place. The fundamental law of Love is to attract to itself its own; that which belongs to it by right of Cosmic ...

... The whole country becomes a lake from which the villages, built on eminences, emerge like little islands. The water recedes in September; by December it has returned to its proper channel. Everywhere has been left a fertile, alluvial bed which serves the purpose of fertilization. On the softened earth the peasant sows his crop with almost no labor. The Nile, then, brings both water and soil to Egypt; if the river should fail, Egypt would revert, like the land on either side ...

... large nor so well coloured as the first, but still fertile eggs that were duly hatched. But for the removal of the first set, these subsequent eggs would never have been developed or laid. Now, the theory has always been that the contact of the sperm- and germ-cells causes the development and fertilization of the latter. In these cases no fresh accession of sperm-cells was possible, and hence it would seem as if in some birds the female organs were able to store up living sperm-cells, which only work to fertilize and develop ...
